IMPROVEMENT IN COLTERS.

Specification forming part of Letters Patent No. l 74,736,6ated March14, 1876; application tiled T I January 22, 1876. V

To all whom it may concern I I Be it known that I, KINY'oN W. MANWAR-ING, of'Oouncil Blufl's, Pottawattamie county, Iowa, have invented a newand Improved Rolling Golter, of which the following'is a specification IMyin'vention consists in mounting the colter, between two right and leftnut-collars, on a shaft which revolves on end bearings in the yoke whichattaches the colter to the plow. The objects are to adjust the colteralong the shaft readily for wide or narrow c11ts,and to arrange thebearings so as to withstand wear and exclude the dust better than whenthe colter revolves on a stationary shaft, as commonly arranged. In thecommon arrange ment the yoke has to be sliiftedon the plowbeam to varythecolter for varying the width of the cuts, which involves moreexpensive construction than this plan, and the contrivance is moredifficult to adjust.

Figure l-is a side elevation, and Fig. 2 is a sectional elevation, of myimproved roller-colter contrivance.

Similar letters of reference indicate corresponding parts.

--A is the colter, B, the shaflg-G, the screw- 7 collar, andD the yokeby which the colt-er is The combination, with roller colter A, of

right and left screw-shaft B, screw-collars (J, and yoke D, arrangedsubstantially as and for the'purpose specified.
